METHOD OF MAKING GENAMENTAI: BODIES 0F EAR-RINGS.

Specification of Letters Patent.

Application filed November 30, 1918. Serial No. 264,876.

To all whom it may concern:

Be it known that we, ROBERT C. GIBBS and J OSEPH ATKINSON, both citizensof the United States, residing, respectively, at East Providence andCranston, in the county of Providence and State of Rhode Island, haveinvented certain new and useful Improvements in Methods of MakingOrnamental Bodies of Ear-Rings, of which the following is aspecification.

Our invention relates to the manufacture of earring bodies, andparticularly to such bodies as are crescent shaped in elevation.

Heretofore it has been regarded as necessary to stamp up two separatecrescent shaped plated shells, and then solder them together at theiredges, thereby leaving seams on the inner and outer peripheries, whichrequired a replating of the article to temporarily cover; and throughwhich acids of the finishing solutions finally percolated and discoloredthe plating. By old methods also the ends of the bodies had to be leftunclosed so that there was admitted through such openings theobjectionable liquid solutions.

Such methods also involved the discoloration due to soldering heat, andinvolved.

such sequence of steps as form the subject matter of the appendedclaims.

In .the accompanying drawings which form a part of this specification,and in which like reference characters indicate lik parts throughout theviews,

Figure 1 is a side elevation of the preliminarily assembled parts of thenew body,

Fig. 2, a longitudinal section of the same after swaging,

Fig. 3, a side elevation after trimming,

Fig. 4, a side elevation partly in longitudinal section, of the sameafter the bending operation and the insertion of the rod,

Fig. 5, a like elevation after shortening the rod, and

Fig. 6, a side elevation of the completed body with an ear wireattached.

In constructing the body a rod 8 is placed gagement with the rod, at thesame time elongating and tapering the tube toward its ends. The portionsofthe rod 8 projecting beyond the shell are now out oflf and the memberappears as shown in Fig. 8.

The member 10 is next bent up on an arbor or otherwise into crescentshape as shown in Fig. 4. The ends of rod 8' are shortened by a drill orotherwise leaving cavities 13 and 14 in the ends of the body, butleaving the wall of the body near its ends in tight or sealed contactwith the rod, as at 16. This prevents all acids or other finishingliquids, in which the body is sub- 7iequently immersed, from accesswithin the The body may be drilled to form perfora tions 18 to receivethe pintle pin 19 of the ear wire 20 which enters the opening 14.

The body 10 is entirely seamless.

If preferred or if various cross sectional shapes of body are desired,the member after receiving the form shown in Fig. 4 is com-' pressed indies of the corresponding cross sectional contour.

We claim 1. The method of forming the ornamental body of an earringconsisting in inserting a rod loosely in a tube, next compressing theend portions of the tube upon the rod, then bending the tube into theform of an incomplete ring, and finally in removing the extremities ofthe rod to form cavities in the ends of the tube.

2. The method of forming the ornamental body of an earring consisting ininserting a rod loosely in a tube, next compressing the end portions ofthe tube upon the rod, and then bending the tube into the form of anincomplete ring.

3. The method of forming the ornamental body of an earring consisting ininclosing the intermediate portion of a rod in a noncontacting tube,next by compression im Patented Dec. 16, 1919.

parting a double taper to the tube and forcing the ends thereof intocontact with the rod, and finally bending the tube and rod into the formof an incomplete ring.

4. The method of forming the ornamental body of an earring consisting inloosely inserting into a tube a rod of greater length than the tube, andnext by compression elongating and. tapering the tube until the ends ofthe tube are in contact with the rod.

In testimony whereof we have atfixed our signatures.
